如何使用 xlwt 和 xlrd 将每五行放入一个 sheet？

Question

现在我只能将14行数据全部保存到Sheet1。我想把每 5 行放在一个 sheet 中，例如：

现在我的代码是这样的：

import xlwt
import xlrd
from xlutils.copy import copy
myyear = '2018'
myweek = '10'
mycd='1001'
fileName = myyear + myweek + '.xls'
workbook = xlwt.Workbook(encoding='UTF-8')
worksheet = workbook.add_sheet('sheet1')
worksheet.write(0, 0, label='year')
worksheet.write(0, 1, label='week')
worksheet.write(0, 2, label='CD')
worksheet.write(0, 3, label='keyword')
worksheet.write(0, 4, label='importance')
savePath = r'D:/' + fileName
workbook.save(savePath)
rexcel = xlrd.open_workbook(savePath)
rows = rexcel.sheets()[0].nrows
excel = copy(rexcel)
worksheet = excel.get_sheet(0)
current_row = rows
for cmp_noun, value in [[1,1],[2,2],[3,3],[4,4],[5,5],[6,6],[7,7],[8,8],[9,9],[10,10],[11,11],[12,12],[13,13],[14,14]]:
    if current_row<=5:
        worksheet.write(current_row, 0, label=myyear)
        worksheet.write(current_row, 1, label=myweek)
        worksheet.write(current_row, 2, label=mycd)
        worksheet.write(current_row, 3, label=cmp_noun)
        worksheet.write(current_row, 4, label=value)
        current_row += 1
excel.save(savePath)

如何修改代码成为我想要的效果？

Answer 1

我知道怎么做了。代码：

from itertools import zip_longest
import xlwt
def generate_data():
    year = '2018'
    week = '10'
    cd='1001'
    for i in range(1, 14):
        cmp_noun = value = i
        yield (year, week, cd, cmp_noun, value)

def grouper(iterable, n, fillvalue=None):
    args = [iter(iterable)] * n
    return zip_longest(*args, fillvalue=fillvalue)


def generate_workbook(header, data, n=5):
    groups = grouper(data, n)
    workbook = xlwt.Workbook(encoding='UTF-8')
    for i, group in enumerate(groups, 1):
        worksheet = workbook.add_sheet(f'sheet{i}')
        group = filter(None, group)
        populate_sheet(worksheet=worksheet, header=header, data=group)
    return workbook

def populate_sheet(worksheet, header, data):
    for i, column in enumerate(header):
        worksheet.write(0, i, column)
    for row_no, row in enumerate(data, 1):
        for i, item in enumerate(row):
            worksheet.write(row_no, i, label=item)

if __name__ == '__main__':
    name = r'D:/' + '201810.xls'
    data = generate_data()
    header = ['year', 'week', 'CD', 'keyword', 'importance']
    wb = generate_workbook(header=header, data=data, n = 5)
    wb.save(name)
